Title: Composting plant for household wastes - with rotary fermenter, mixer homogeniser and piling device
IPC: C05F17/02
Filed: 1976-11-09
Abstract: Composting plant is intended for transforming household refuse from urban centres into organic manures; the refuse is treated in three stages, by means of three machines. The first receives the organic refuse contained in plastic bags which have been brought to the plant in the lorry. The bags are compressed between two endless conveyor belts and then cut open by a saw; the contents are transferred by conveyor to the second machine, a rotary fermenter where they are sterilised and homogenised into a mass; oxygen is admitted through openings. As fermentation proceeds the rise in temp. kills the pathogenic germs. The homogenised material is then introduced into the third machine by a conveyor; it is mixed and inoculated with bacteria which, as fermentation proceeds, converts it into a manure. It is formed into a heap as the machine advances on it wheels to successive positions. Other heaps can be formed parallel with the first. The use of organic manures obtd. in the plant from domestic wastes results in a better enrichment of the soil with agricultural prods. of improved quality, in greater abundance and contg. the necessary vitamins. The biological transformation of the wastes avoids accumulations, suppresses bad smalls, prevents insect infestation and risks of dangerous infections; at the same time it reduces pollution.

Title: Perforating a nonwoven fleece of synthetic fibres - esp. for tearing off in multiwall tubular sack machine
Inventor: TIROUFLET J-P
IPC: D06H7/02
Filed: 1977-01-14
Abstract: Perforations are made in a sheet material consisting of synthetic fibres, esp. non-woven fibres, with the aid of >=1 indented blade which is heated. The blade is rotated around an axis whilst the sheet of fibrous material follows a path at right angles to this axis. In the perforating zone, the fibrous sheet is tensioned between two rollers. At least one of the rollers is supported by a device such as a jack. This is linked to the driving mechanism for the sheet, so that when the sheet is stopped, it is withdrawn out of the range of the blade. Arrangement enables the use of reinforcements of synthetic fibrous material on conventional multiwall sack machines, ensuring that when tension is applied, the sheet of non-woven synthetic fibres tears across the perforations as does the paper, etc.

The half shafts are joined by coaxial shafts (43, 44) with the space in between filled with a viscous fluid. This provides sufficient drag to operate the drive with equal torque on each wheel for normal travel. The whole drive unit is simple and light and requires no mechanical differential.
Patent FR-2344176-A1 (FR)
Title: Power supply using series transistors - has transistors connected between load and rectifying diodes coupled to AC transformers secondary tappings
IPC: G05F1/56
Filed: 1977-03-11
Abstract: The power supply consists of several transistors (Q1-Q5) each connected in series between the load and one tapping point on the ac transformer secondary via rectifier diodes and smoothing capacitors. The emitters of these transistors are connected together at one end of the load. The bases of the transistors are coupled separately via switches to biasing potentials that allow any one of them to be switched on whilst holding the other off. The output voltage therefore depends on which transistor is on. The bias voltage is made dependent on the output voltage for stabilisation. The advantage lies in producing a stable output voltage efficiently.
